Patent number 8508956 is assigned to
The following quote was obtained by the news editors from the background information supplied by the inventors: "The present disclosure generally relates to systems and methods of mounting electrical components and, in particular, modularizing electronics while providing ElectroMagnetic Interference (EMI) shielding.
"Hospitals have a need to provide secure storage for certain medications, such as narcotics and controlled substances, while still making the medications available to care givers. One method of providing this secure storage is the use of Automatic Dispensing Machines (ADMs), which typically contain a microprocessor that is functionally connected to the hospital data systems and lockable drawers and compartments containing the medications. The software of each ADM is normally configured to allow access to the medications only after certain requirements are met, such as verification that the individual requesting the medication is authorized to do so. The ADMs should be continuously operational as hospitals must provide care to their patients 24 hours a day.
"Computer processors and motherboards that may be used in such systems are known to emit electromagnetic radiation across a wide frequency band due to the high frequency digital signals conducted through the circuits of the processor and on the board. To meet regulatory requirements that limit the amount of electromagnetic energy that can be radiated from electronic devices, motherboards are frequently mounted inside conductive enclosures. As electromagnetic radiation is sometimes emitted from conductors connected between the motherboard and other electronic components, the conductive enclosure is often the entire outer case of the electronics. Providing a conductive enclosure of this size with EMI seals around all access openings is more expensive that an enclosure for just the motherboard and makes access to the electronics for repair and replacement more complicated."
In addition to the background information obtained for this patent, VerticalNews journalists also obtained the inventors' summary information for this patent: "There is a need to improve the operation of an ADM by providing an easily-removed modular electronics enclosure that also provides EMI shielding around electronic components that generate EMI and limit the radiated electromagnetic energy from cables that are connected to the electronic components within the enclosure.
"The disclosed system provides a modular electronics enclosure that incorporates EMI shielding for the enclosed electronics as well as reducing the electromagnetic radiation emitted by conductors that connect the enclosed electronics to components outside the shielded volume. In the system, the electronics are mounted on a first sled that forms a part of a shielded enclosure, wherein the first sled couples to an interface board that includes circuitry that matches the impedance of at least one external circuit thereby limiting the electromagnetic radiation emitted by the at least one external circuit.
